TDK EPCOS B59770C0120A070 Alternative, PTC 420V 70 Ohm 1.4A Overcurrent Protection Inrush Current Limiting

AMWEI Ordering Code: AMZ11A-08P70RN420

Leaded Disk Coated PTC Thermistor Appearance Engineering Drawing

Application: Overcurrent protection, overload, short circuit protection, inrush current limiting.
Best suited to meet the requirements for measuring instrumentation and meter circuit overload and short circuit protection.
Error-free operations are assured by rush current.
Circuit is protected until current is turned off.
Restores the original low resistance value automatically once the overload is removed.
Non-contact design leads to long life and no noise.
Durable and strong against mechanical vibration and shock.
