Panasonic, HF Varistor 5A, Clamping 43V, Varistor 27V, SMD / 8173544

Panasonic ZNR HF Series SMD Surge Absorbers. Panasonic ZNR HF Series surface mount surge absorbers are suitable for flow or reflow, iron soldering. Moulded construction protects the surge absorbers from 'soldering heat shock'. HF surge absorbers are part of the Zinc-oxide Non-Linear Resistor (ZNR) range. Saving cost and board space, they can perform the same function as two back to back zener diodes and a parallel connected capacitor. Meets requirements for load dump surge test (JASO D 001-94) Meets requirements for load dump surge test ISO7637-2 and ISO16750-2 Compact size High reliability For automotive (DC12 V) requirements Surface mount Protective coating. Applications. HF surge absorbers are recommended for automotive applications to protect against load dump surges in ECUs.
