Molex Micro-Fit 3.0mm Pre-Crimped Terminal Cable — 22AWG UL1007 PVC, 3A / 300V
The Molex Micro-Fit 3.0mm pre-crimped terminal cable is the professional-grade wiring solution for high-density signal and power harness assembly. Featuring genuine Molex Micro-Fit 3.0 crimp terminals and a 22AWG UL1007 PVC conductor rated at 3A / 300V, this cable delivers the connector reliability demanded by server power distribution, industrial control systems, telecommunications equipment, and high-performance computing applications.
The Micro-Fit 3.0 connector system (Molex 43645 / 43025 series) is the industry standard for high-density connections in space-constrained applications — offering a 3.0mm pitch that packs more contacts into a smaller footprint than traditional 4.2mm Mini-Fit Jr. connectors. The bare terminal ends allow direct insertion into pre-installed Micro-Fit 3.0 housings for custom harness assembly.
Key Features
- Genuine Molex Micro-Fit 3.0 crimp terminals — precision-stamped contacts for reliable, low-resistance connections in Micro-Fit 3.0 housings (43645 / 43025 series)
- 3.0mm pitch — high-density connector pitch; more compact than 4.2mm Mini-Fit Jr.
- 22AWG UL1007 PVC insulation — rated 80°C, 300V, flexible and durable
- 3A / 300V rating — suitable for signal and moderate power lines
- Pre-crimped factory assembly — consistent, reliable crimp quality
- RoHS compliant
Typical Applications
- Server and data center backplane harness assembly
- Industrial control systems — PLC power supply and I/O module wiring
- Telecommunications equipment harness assembly
- High-performance computing custom cable fabrication
- Medical equipment power supply and control harness
- Custom harness assembly for Micro-Fit 3.0 housing systems
Micro-Fit 3.0 vs. Mini-Fit Jr. 4.2mm
- Micro-Fit 3.0mm (this product): 3.0mm pitch, 3A per contact, 300V — higher density, more compact; ideal for server, telecom, and space-constrained applications
- Mini-Fit Jr. 4.2mm: 4.2mm pitch, 9A per contact, 600V — higher current per contact; ideal for ATX power supplies and high-current applications

Frequently Asked Questions
Product & Compatibility
What is the difference between JST PH, XH, ZH, and SH connectors?
JST connectors differ primarily in pitch (pin spacing): SH = 1.0mm, ZH = 1.5mm, PH = 2.0mm, XH = 2.5mm. Smaller pitch connectors are used in compact electronics like drones and wearables, while larger pitch connectors suit general prototyping and power applications. Always verify pitch before ordering to ensure compatibility.
Are your connectors compatible with standard Arduino and Raspberry Pi projects?
Yes. Our DuPont 2.54mm connectors are the industry standard for Arduino, Raspberry Pi, and most development boards. JST PH 2.0mm is widely used for LiPo batteries in RC and robotics projects. We recommend checking your board's datasheet to confirm the exact connector type and pin count required.
What wire gauge (AWG) should I choose for my application?
Wire gauge depends on current load: 28–30 AWG suits signal lines up to 0.5A; 24–26 AWG handles 1–3A for moderate power; 22 AWG is suitable for up to 5A. For high-current applications, always use appropriately rated wire and connectors. Our product listings specify the AWG and rated current for each cable.
What is the difference between UL1007 and Silicone wire?
UL1007 is a PVC-insulated wire rated for 80°C and 300V, suitable for most indoor electronics applications. Silicone wire is rated for higher temperatures (up to 200°C), is more flexible, and performs better in harsh environments or high-vibration applications such as RC vehicles and industrial equipment.
Orders & Customization
Can I order custom cable lengths or connector configurations?
Yes. We offer custom wire harness solutions including custom lengths, connector types, pin counts, and wire colors. Please contact us via the Contact page with your specifications and we will provide a quote within 1–2 business days.
Do you offer bulk or wholesale pricing?
Yes. Volume discounts are available for orders of 50 units or more. Please reach out through our Contact page with your requirements for a customized wholesale quote.
How do I know which connector polarity or pin orientation to order?
Always refer to your device's datasheet or existing connector for pin 1 orientation. Our product images include wiring diagrams where applicable. If you are unsure, contact us with your device model and we will help identify the correct part.
Shipping & Returns
How long does shipping take?
Standard international shipping typically takes 7–15 business days depending on destination. Expedited options are available at checkout. Orders are processed within 3 business days. Tracking information is provided via email once your order has shipped.
