Product Description

Panasonic ERZHF2M270 HF series varistor is a surface mount metal oxide surge absorber designed for high reliability in electronic circuits, particularly for automotive applications. It offers a clamping current rating of 5 A and a clamping voltage of 43 V, capable of protecting sensitive components from transient voltage surges effectively. The compact dimensions (8 mm length, 4.5 mm height, 6.4 mm depth) enable efficient use of PCB space and compatibility with flow or reflow soldering processes.

The varistor features a moulded construction that shields it from heat shock during soldering, ensuring manufacturing robustness. With a maximum DC voltage rating of 16 V and a maximum operating temperature of 125°C, this device sustains electrical and thermal stresses encountered in automotive environments. It meets stringent automotive standards, including load dump surge tests specified by JASO D 001-94, ISO7637-2, and ISO16750-2, thereby ensuring protection for electronic control units (ECUs) and other automotive electronics.

Its Zinc-oxide Non-Linear Resistor (ZNR) technology enables it to perform surge absorption equivalent to dual zener diodes and capacitors, saving circuit complexity and cost. RoHS compliance certifies its adherence to environmental and safety norms. This varistor is ideal for industrial, automotive, and electronic manufacturing applications requiring reliable surge protection in compact form factors.

Compact surface mount design for efficient PCB integration. High surge current rating of 5 A. Heat-resistant moulded construction. ZNR technology reduces circuit complexity. Suitable for automotive load dump surge protection.

Meets international load dump surge standards. RoHS compliant ensuring environmental safety. High maximum operating temperature of 125°C. Optimized dimensions for space saving.
