Low profile VRM connectors for 1U servers handle up to 130 amps of VRM 10.0
and 10.1
Today’s high performance microprocessors require highly regulated DC-to-DC power conversion
located near the processor. The Molex low profile VRM (Voltage Regulator Module) connector is
specifically designed to handle high output currents at high slew rates. This connector was designed
in conjunction with a high performance power silicon manufacturer who also designed a low profile
module for this connector in 1U applications. Major VR makers are currently implementing modules
for this connector.

Features and Benefits
s
Includes 20 signal contacts for VR control
and 72 power contacts for 12 volt input
current and up to 130.0A of V0 output and
return
s
Open housing allows for air flow to cool the
contacts much like a heat sink
s
Low loop inductance design is ideal for high
slew rates characteristic of today’s high
performance VRs
s
s
s
Through hole pin field is designed for easy
route through of signals between processor
and chip set
Four fork locks secure the connector to PCB
to resist shock and vibration
Unique reverse angle latch notch feature
retains the VR securely during shock testing
