Panasonic 120 μF Polymer Capacitor 50V dc, Surface - EEHZC1H121P

Panasonic Polymer Capacitor, 120μF Capacitance, 50V Voltage - EEHZC1H121P

This polymer capacitor is a surface-mount electrolytic component designed for demanding electronic and automotive control systems. It provides decoupling and energy storage at medium voltage levels while tolerating elevated temperatures and continuous ripple conditions, making it suitable for Compact assemblies in industrial automation and vehicle electronics.

Features and Benefits:

• 120μF capacitance delivers stable bulk storage for power rails
  50V rated voltage supports medium-voltage circuits safely
  125°C maximum temperature allows high‑temperature operation
  1.6A ripple current handles substantial AC stress on supply lines
  60μA leakage current minimises standby losses in long duty cycles
  ±20% tolerance offers predictable performance across batches

Applications

• Suitable for automotive power-supply smoothing in ECUs
  Ideal for DC to DC converter output filtering in automation equipment
  Used with motor drive electronics requiring high ripple handling
  Can be used for backup power buffering in control modules

What mounting considerations apply for PCBA assembly?

It is a surface-mount device supplied in taping format and requires solder pads matching its lead pitch for reliable reflow placement.

How long can it operate continuously at elevated temperatures?

The component is specified for a lifetime of 4000h when subjected to its rated operating conditions, including high-temperature ambient.

What environmental temperature range can it tolerate during operation?

It will function across a wide span from -55°C up to its 125°C maximum operating temperature.

How does polarity affect installation and circuit design?

The device is polarised, so correct orientation on the board is essential to prevent malfunction or damage when exposed to rated voltages.

What physical envelope and package type does it require on the PCB?

The component has a nominal diameter of 10mm and a height of 12 mm, and is packaged for surface-mount placement.
