DF63-3S-3.96C Connector Cable 3.96mm terminal wire Internal Power Wiring Harness 16AWG Silicon Cable DF63A-1618SCF Terminal Wire

Product Description

This pre-crimped finished wire-to-board power assembly is built with complete authentic HRS DF63 series matched components, all parameters cross-checked against Hirose official catalog and datasheet:

Female Receptacle Housing PN: DF63-3S-3.96C, 3-circuit single-row crimp socket, 3.96mm center pitch, black high-temperature PBT plastic
Dedicated Crimp Terminal: DF63 series tin-plated thick phosphor bronze multi-point contact, compatible with AWG16~AWG22 power stranded wire
Mating PCB Headers: DF63 vertical through-hole male wafer / DF63 right-angle through-hole male wafer for PCB power board soldering
Matching Wire Spec: AWG16~AWG22 flexible power cable, insulation outer diameter φ1.8~φ2.8mm

As a flagship EnerBee power connector series from Hirose, DF63-3S-3.96C is optimized for medium-high current power transmission. The exclusive tactile positive lock structure sends an obvious "click" sound after full mating, effectively avoiding incomplete mating hidden danger that causes overheating burnout during long-term power operation. Molded physical polarization keys block reverse insertion and cross-model mis-mating, completely eliminate PCB short-circuit risks in mass production assembly.

Internal molded lance structure locks crimp terminals firmly inside the housing, preventing terminal back-out caused by wire pulling and equipment vibration. Square wide-surface male pins on the PCB header and multi-point female contacts jointly reduce contact resistance, minimizing temperature rise under continuous heavy load. The tapered housing base supports potting resin filling up to 5mm height, suitable for sealed power supply module design.

Matched multi-color coded power cables clearly distinguish positive, negative and ground power circuits. Every finished harness undergoes strict full inspection before shipment: continuity test, terminal pull retention force test, 2200V AC high voltage withstand test, vibration aging test and long-time load temperature rise test. We supply single-end DF63 finished cables and cross-type conversion harness (matched with terminal blocks, aviation plugs) OEM mass customization solutions for power supply, industrial automation and medical equipment manufacturers.

FAQ

Q1: What series, pitch and pin count does HRS DF63-3S-3.96C belong to?

A: It belongs to Hirose EnerBee™ DF63 high-current wire-to-board connector series, 3-position single-row female crimp housing with fixed 3.96mm center pitch, all data sourced from official Hirose DF63 datasheet.

Q2: What maximum continuous current can each pin bear?

A: Current capacity varies by wire gauge: AWG16 wire supports up to 12A continuous load, AWG18 for 10A, AWG22 for 8A; specially designed for medium-current internal power supply circuits.

Q3: What is the core advantage of the DF63 series tactile click lock?

A: It produces obvious click feedback after full mating, which can visually and audibly confirm complete insertion, fundamentally avoid hidden danger of incomplete mating that leads to power contact overheating.
