Hammond 167V5 100VA Filament Transformer, 5V Center-Tapped 20A

The 167V5 is a low voltage filament and rectifier power transformer from the 167 Series, rated at 100 VA. It steps a 115 VAC, 60 Hz line down to a 5 V center-tapped secondary capable of 20 A RMS, which suits OEM engineers and repair technicians who need a high-current, low-voltage winding inside equipment chassis.

Like every 167 Series unit, the 167V5 uses an enclosed construction with a four-hole chassis mount. A dual bobbin design separates the primary and secondary so that no electrostatic shield is required, and the insulation system is Class B, rated to 130 degrees C. Each transformer is Hi-Pot tested at 2,000 V RMS.

Connections are made through flying leads that are a minimum of 6 inches long, so the part can be wired directly to a terminal strip, rectifier or filament circuit without extra pigtails. The centre tap on the 5 V secondary gives a mid-point reference for full-wave centre-tapped rectification or balanced filament supplies.

The 167V5 is UL listed under file E50394 and CSA certified under file 209651, and is marked RoHS and REACH compliant. Shipping weight is 3.4 lbs (1.54 kg). Detailed outline dimensions for this part number are not listed in the series ordering table, so confirm the mounting footprint against the manufacturer drawing before cutting chassis holes.
