PolySwitch Resettable Devices

Radial-leaded Devices

TE Circuit Protection’s PolySwitch radial-leaded products

represent the most comprehensive and complete set of

PPTC products available in the industry today.

• RGEF series for hold currents up to 14A

• RHEF series for flatter thermal derating and

operating temperatures up to 125°C

• RUEF series for balance of voltage rating (30V) and

hold current (up to 9A)

• RUSBF series for fast time-to-trip and low-resistance

computer applications

• RXEF series for low hold currents (down to 50mA)

and high voltage rating (up to 72V)

• RKEF series for balance of voltage rating (60V) and

hold current (up to 5A)
