HWCT5A/5mA Micro Current Transformer

High-Precision 1000:1 Current Ratio: Precisely steps down 0 - 5A AC primary current to a proportional 0 - 5mA secondary current output (1000:1 turn ratio) for micro-controller sampling.

Compact THT Printed Circuit Board Design: Compact micro-size plastic housing equipped with PCB through-hole solder pins for direct mounting onto target control boards.

Galvanic Isolation Protection: Completely isolates high-voltage primary AC lines from low-voltage sampling circuits, protecting downstream microcontroller ADCs and host processors.

Encapsulated Flame-Retardant Resin Enclosure: Housed in a fully sealed epoxy resin shell with high insulation resistance, protecting internal core copper windings from moisture and mechanical vibration.

High Linearity & Low Phase Shift: Provides low phase shift and high conversion accuracy across standard 50Hz / 60Hz AC grid mains frequencies.

Housing & Board Material: Flame-retardant ABS blue plastic casing filled with high-dielectric epoxy resin and tinned through-hole copper leads.

Technical Specifications:

Primary Rated Input Current: 0A - 5A AC.

Secondary Rated Output Current: 0mA - 5mA AC (1000:1).

Non-linearity: ≤0.2%.

Color: Blue Plastic Case with Gold/Silver Pin Contacts.

Usage Advice: Pass primary AC live wire through center aperture hole; connect secondary output pins across a sampling burden resistor (R_B) to generate a proportional AC voltage for microcontroller ADC sampling.

Maintenance: Ensure secondary pins remain securely soldered; keep the component body dry, clean, and free of metallic dust or solder flux residue.

Essential Micro AC Current Sampling Transducer: Position as a compact current transformer for micro-energy meters, appliance power consumption loggers, sub-metering boards, and smart power strips.

Highlight Compact PCB Mounting & High Precision: Emphasize how direct through-hole PCB integration (1000:1 ratio) eliminates bulky external current clamps while maintaining precision analog current conversion (0.2% non-linearity).
