Product Features
- Dual‑row 3.0mm pitch, right‑angle thru‑hole soldering termination, horizontal outgoing cable release
- Integrated polarization key: avoid reverse mating, protect PCB & harness from damage
- Snap‑in plastic locking peg: firmly lock header onto PCB, resist vibration shock
- High‑performance LCP plastic housing, withstand IR reflow soldering high temperature peak
- Multiple plating selections: matte tin for cost‑sensitive projects; selective gold for high‑cycle / corrosive environment
- Fully shrouded pin design, prevent accidental short‑circuit by foreign debris
- Standard mating partner: 43025 female receptacle series, complete Micro‑Fit 3.0 interconnect ecosystem
Product Advantages
- Layout‑Friendly: Right‑angle horizontal exit greatly reduces vertical height requirement on PCB, ideal for narrow cabinet & slim device enclosure
- Mass‑Production‑Ready: Tight coplanarity control reduces soldering defect rate; tray & reel packaging support automatic assembly line
- Cost‑Flexible: Tin‑plated version for cost‑sensitive consumer equipment; selective gold‑plated for industrial / high‑vibration long‑life equipment
- Anti‑Failure Design: Polarization key + shrouded pin + PCB lock peg collectively prevent mis‑plug, loose connection and short‑circuit risk
- Full Ecosystem Compatibility: Direct mate with standard Micro‑Fit3.0 43025 female housing, no redesign effort for existing Molex‑based projects
- High‑Temperature Resistant: LCP housing avoids plastic melt during wave / reflow soldering process, less assembly reject rate
Application
- Industrial automation: PLC modules, servo drives, industrial controllers, sensor power‑signal connection
- Datacom & networking: Routers, switches, small‑size server internal power distribution
- Consumer electronics: Household appliances, power supply units, battery management modules
- Medical equipment: Non‑implant medical device internal wiring connection
- New‑energy: Small power battery packs, charging control boards
- Smart hardware: IoT gateway, embedded control board, robotics internal wiring
Customer Selection Guide
- Pin count selection: Confirm circuit quantity; select 6P /8P /12P according to your schematic. Keep spare circuit position for future upgrade if possible.
- Plating selection:
- Matte tin: Indoor general environment, low mating cycles (<30 times), cost priority
- Selective gold plating: High vibration, humid environment, repeated mating cycles, long service‑life industrial equipment
- PCB layout note: This is right‑angle thru‑hole header, reserve lock‑peg hole on PCB footprint; strictly follow datasheet pin layout to avoid soldering short.
- Mating check: Must pair with Micro‑Fit3.0 43025‑series female housing, do NOT mix with other 3.0‑pitch non‑Micro‑Fit series.
- Current derating: Derate current under high ambient temperature; do not run full 8.5A rating continuously above 85 ℃.
- Assembly reminder: Do not apply excessive side force after mating; lock peg must fully insert into PCB locating hole.
FAQ
1. Q: Do you have a catalogue? Can you send me the catalogue to check all your products?
A: Yes, you can contact us online or send an Email to get the catalogue.
2. Q: I can't find the product in your catalogue, can you make this product for me?

A: Weaccept T/T(Wire transfer), Western Union, and PayPal. Please make sure that we can receive the same amount as the Invoice. And you can pay in RMB. No problem.
7. Q: How about your company's quality control
A: Strictly obey ISO9001, IQC, OQC, IPQC, QA occupy 10% of our Quality department. All of our products will be tested by CCD.
8. Q: I need your price list of all your products. Do you have a price list?
A: We do not have a price list of all of our products. Because we have so many items, it's impossible to make all of their prices on a list, and the prices are always changing because of the material cost and quantity. And you can give us a list of all of the items you need; we will confirm carefully one by one and give you a specification and price list
9. Q: Can you make customized products and customized packing?
A: Yes. We have made a lot of customized
products for our customers formerly (mainly wire harnesses). About customized packing, there is no problem for we put your logo or other information on the package. Just have to point out that it incurs additional cost.
10. Q: What certificates do you have?
A: CE, CQC, UL, ISO9001, ISO14001, IATF16949, ISO45001, QC080000, etc.
