Extras ▼

 

The U52 is a very useful rectifier with its 250 mA current rating and PIV of 1,400 Volts.
This example is of modern construction, with a glass disc base replacing the old pinch that was used in the original late 1930's valves.
The maximum reservoir capacitor is 16 µF and the minimum series resistance is 180 Ohms.
The wide glass tube envelope is 36 mm in diameter and, excluding the IO base pins, is 87 mm tall.
References: Datasheet, 1040 & 1043. Type U52 was first introduced in 1938.
