UL 1007 22 AWG Tinned Copper 80°C 300V Wire — Electronic Hook-Up Wire, MOQ 100m
UL Style 1007 in 22 AWG tinned copper is the dominant wire specification for consumer electronics internal wiring, PCB interconnect harnesses, and low-current signal and power circuits in compact electronic enclosures. At 22 AWG — approximately 0.33mm² nominal cross-section — the conductor provides adequate current capacity for the majority of low-current internal electronics circuits while maintaining the compact diameter required for high-density wiring harness routing inside consumer electronics, telecommunications equipment, and industrial control electronics.
The tinned copper conductor specification is the default for electronic hook-up applications — the tin coating provides superior solderability for PCB termination and oxidation resistance for long-term connection reliability. Every spool ships with the UL Recognized Component Mark and complete UL compliance documentation for electronics product certification.

Why 22 AWG Tinned Copper — Electronics Hook-Up Context
22 AWG at 0.33mm² nominal cross-section is the standard wire size for electronics internal hook-up wiring carrying currents in the 0.5–3A range — covering the majority of internal power distribution and signal circuits in consumer electronics, computing equipment, telecommunications hardware, and industrial control electronics. At 22 AWG, the wire is compact enough for high-density harness routing through tight electronic enclosure clearances while providing adequate current capacity for typical low-voltage DC power circuits and AC control circuits within electronic equipment.
The tinned copper conductor specification is critical for electronics applications for two reasons. First, solderability: the tin coating allows direct soldering to PCB pads, terminal posts, and connector pins without flux pre-treatment, ensuring reliable solder joints in automated and manual assembly processes. Second, oxidation resistance: bare copper oxidizes over time, increasing connection resistance at solder joints and crimp terminations — the tin coating prevents conductor oxidation, maintaining stable connection resistance over the equipment service life. For electronics hook-up applications, tinned copper is the standard specification and bare copper is rarely used.
For the 600V Peak electronic use marking: in switch-mode power supply applications where rectified DC peak voltages in the power factor correction and DC bus stages exceed 300V but remain below 600V peak, specify the “600V Peak — For Electronic Use Only” marking at order time. This provides the required UL documentation for electronics safety review without any change to the physical wire construction.
Typical Applications — UL 1007 22 AWG Tinned Copper
- Consumer electronics internal wiring harnesses — internal signal and power distribution wiring in consumer electronics, audio equipment, set-top boxes, and small appliances where 22 AWG provides the standard current capacity for internal DC power rails and signal circuits, and the tinned copper conductor ensures reliable solder termination in automated PCB assembly.
- PCB-to-PCB interconnect wiring — board-to-board connection wiring, power distribution between PCB assemblies, and inter-module signal routing inside electronic equipment enclosures where 22 AWG tinned copper provides reliable soldered or crimped connections between circuit boards in multi-board electronic equipment designs.
- Switch-mode power supply internal wiring — secondary output wiring, transformer lead connections, and internal DC rail distribution in switch-mode power supplies and AC adapters where 22 AWG covers the current capacity of low-power supply outputs and the tinned copper conductor ensures reliable solder joints to transformer terminals and PCB connection points.
- Telecommunications and networking equipment wiring — internal power and signal wiring in telecom base station equipment, networking hardware, and industrial communication equipment where 22 AWG tinned copper provides the standard internal hook-up wire specification for low-current circuits requiring UL recognition for equipment product certification.
Related AWG Sizes — UL 1007 Family
Buyers specifying UL 1007 22 AWG commonly also order: UL 1007 24 AWG (smaller conductor for lower-current signal circuits and high-density harness routing), UL 1007 20 AWG (larger conductor for higher-current power distribution circuits within electronics), UL 1007 18 AWG (upper power circuit range in the UL 1007 family), and UL 1015 16 AWG (for circuits requiring 600V rating where the 300V rating of UL 1007 is insufficient).
