## Type YM Series Thermometrics PTC Thermistors 

## **Description** 

## **Applications** 

Thermometrics YM Series consists of a range of radially-wired PTC disc thermistors with silicone resin coating. 

- Designed for general purpose over-current, overvoltage and direct over-temperature protection 

## **Features** 

## **Packaging** 

- Fast switching times 

- Operation up to 265V rms 

All types in the YM range are available loosepacked, as shown in the drawing. Devices are also available on bandolier (tape & reel): types with diameter a <12 mm comply with IEC 286-2. 

- Wide range of operating current levels 

- Excellent stability 

To identify the packaging required, replace N in the product codes shown in table as follows: 

- Fail-safe operation 

## **YM** 

- Solid state 

- High performance barium titanate ceramic 

- Suitable for automatic PCB insertion
