Damage resulting from the installation or use of any accessory or attachment not approved by MTD Products Inc. for use with the product(s) covered by this manual will void your warranty as to any resulting damages.

Normal wear parts or components thereof are subject to separate terms as follows: All normal wear part or compo- nent failures will be covered on the product for a period of 90 days regardless of cause. After 90 days, but within the two year period, normal wear part failures will be covered ONLY IF caused by defects in material or workmanship of OTHER component parts. Normal wear parts and compo- nents include, but are not limited to, belts, blades, blade adapters, grass bags, rider deck wheels, seats, snow thrower skid shoes, shave plates and tires. Batteries are covered by a 90-day limited replacement warranty.

HOW TO OBTAIN SERVICE: Warranty service is available,

WITH PROOF OF PURCHASE THROUGH YOUR LOCAL AUTHORIZED SERVICE DEALER. To locate the dealer in your area, please check for a listing in the Yellow Pages or contact the Customer Service Department of MTD PROD- UCTS INC by calling 1-800-800-7310 or writing to P.O. Box 368022, Cleveland, Ohio 44136-9722.

This limited warranty does not provide coverage in the following cases:

a. The engine or component parts thereof. These items carry a separate manufacturer’s warranty. Please refer to the applicable manufacturer’s warranty on these items.

b. Log splitter pumps, valves and cylinders have a sepa- rate one year warranty.

c. Routine maintenance items such as lubricants, filters, blade sharpening and tune-ups, or adjustments such as brake adjustments, clutch adjustments or deck adjustments; and normal deterioration of the exterior finish due to use or exposure.

d. MTD does not extend any warranty for products sold or exported outside of the United States of America, its possessions and territories, except those sold through MTD’s authorized channels of export distribu- tion.

No implied warranty, including any implied warranty of merchantability or fitness for a particular purpose, applies after the applicable period of express written warranty above as to the parts as identified. No other express warranty or guaranty, whether written or oral, except as mentioned above, given by any person or entity, including a dealer or retailer, with respect to any product shall bind MTD. During the period of the War- ranty, the exclusive remedy is repair or replacement of the product as set forth above. (Some states do not allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you.)

The provisions as set forth in this Warranty provide the sole and exclusive remedy arising from the sales. MTD shall not be liable for incidental or consequential loss or damages including, without limitation, expenses incurred for substitute or replacement lawn care ser- vices, for transportation or for related expenses, or for rental expenses to temporarily replace a warranted product. (Some states do not allow the exclusion or limita- tion of incidental or consequential damages, so the above exclusion or limitation may not apply to you.)

In no event shall recovery of any kind be greater than the amount of the purchase price of the product sold. Alteration of the safety features of the product shall void this War- ranty. You assume the risk and liability for loss, damage, or injury to you and your property and/or to others and their property arising out of the use or misuse or inability to use the product.

This limited warranty shall not extend to anyone other than the original purchaser, original lessee or the person for whom it was purchased as a gift.

How State Law Relates to this Warranty: This limited warranty gives you specific legal rights, and you may also have other rights which vary from state to state.

31AH5C3F401, 31AH5Q3G401 specifications

The MTD 31AH5Q3G401 and MTD 31AH5C3F401 are advanced power MOSFETs designed for various high-efficiency applications. These components are notable for their superior performance in energy conversion and management, making them ideal for use in automotive, industrial, and consumer electronics sectors.

One of the main features of the MTD 31AH5Q3G401 is its low on-resistance (Rds(on)), which significantly contributes to enhanced energy efficiency. Low Rds(on) translates to lower conduction losses during operation, leading to reduced heat generation. This characteristic is crucial in applications where thermal management is a concern, allowing designers to minimize the size of heat sinks and cooling systems.

The MTD 31AH5C3F401 complements this with a fast switching speed, which is essential for high-frequency applications such as switch-mode power supplies (SMPS) and DC-DC converters. The rapid transition from on to off state results in decreased switching losses, allowing for higher overall efficiency in power conversion processes.

Both models utilize a robust silicon technology that enhances their reliability and durability under various operational conditions. Their maximum voltage ratings can easily accommodate voltage transients encountered in automotive applications, ensuring they can handle high-stress environments without compromising performance.

In terms of packaging, the MTD 31AH5Q3G401 and 31AH5C3F401 are available in compact forms, enabling designers to save space on PCBs while maintaining a high power density. The integration of thermal management features within the package reduces thermal resistance, further aiding in effective heat dissipation, which is critical in prolonged use.

A common characteristic of both devices is their ability to operate in a wide range of temperatures, which makes them suitable for both outdoor and indoor applications. They are capable of delivering reliable performance across different environmental conditions, enhancing their usability in various sectors.

In summary, the MTD 31AH5Q3G401 and 31AH5C3F401 are exemplary components featuring low on-resistance, fast switching capabilities, robust silicon technology, and compact packaging. These attributes position them as ideal choices for designers looking to enhance the efficiency and reliability of their electronic systems while managing thermal challenges effectively.
