PK-HVg-22A9 is a superminiature high voltage (400V) generator module for Geiger-Müller tubes. 

The module is for use in geiger counters and dosimeters where portability, very small size and weight, very low power consumption and stability is required. 

Specifications:

supply voltage: 3-5.5V  

High voltage:  400V Practically all popular Geiger-Müller tubes are supported. Current limiting resistor is not installed. 

Low quiescent (standby) current: ~ 7μA

Low ripple:  >2.5% 

Working temperatures: -20 to +60ºС

Dimensions: L18mm x D11mm x H3.5mm

Pin from left to righ spacings from the left side:

HV pin 0mm, GND pin 2.5mm, Vcc 7.5mm

Vcc pin to the right side is 8.5mm

Weight: 1g

Three pin module: pin 1 HV, pin 2 GND, pin3 positive input voltage

Currently shipping modules are produced on the factory made PCBs (green color solder masked) and encapsulated in epoxy for isolation purpose.

Color of the resin may vary (transparent or black - depending on the current supply)

Each module is professionally tested after manufacture and before shipping.
