Product description
K-CUT B1203S-1W 12 V to 3.3 V DC-DC converter - Isolated Step-down Power Module
Do you design sensitive microprocessor systems, industrial buses, IoT modules or communication interfaces and struggle with interference or ground loops? The K-CUT B1203S-1W is a compact, highly reliable step-down DC-DC power converter with galvanic isolation of input and output. This miniature module in a SIP housing can transform fluctuating or jammed 12 V DC voltages into stable, clean 3.3 V with a maximum output of 1 W.
By isolating the circuitry, it effectively separates the logic power supply from the power supply (e.g., relays, motors, or switching power supplies), protecting expensive microcontrollers from voltage spikes and fatal damage.
Main advantages:
- Complete galvanic isolation (Isolated Module).
- Stable 3.3V output: ideal level for powering modern 3.3V microcontrollers (ESP32, STM32, Arduino Due, Raspberry Pi Pico) and wireless modules (Wi-Fi, Bluetooth, LoRa).
- Compact SIP housing: miniature size with single in-line pins (Single In-line Package) saves PCB space and allows easy integration into densely populated boards.
- Efficient Step-down Conversion.
- It serves as a reliable safety barrier between the harsh industrial/automotive 12V environment and sensitive 3.3V digital logic.
Technical Specifications:
- Brand/Manufacturer.
- Model designation: B1203S-1W
- Module Type: Isolated Step-down DC-DC Voltage Converter
- Input Rated Voltage: 12 V DC (range usually $\pm10\%$)
- Output voltage: 3.3 V DC
- Maximum output power: 1 W
- Maximum output current: approx. 303 mA (ideal for MCUs and sensors)
- Isolation voltage: standard 1000 V DC to 1500 V DC (depending on series specification)
- Housing type: SIP (Single In-line Package, plastic housing with pins in a single line)
Ensure maximum stability for your projects, filter out unwanted interference and protect sensitive microprocessors with the K-CUT professional isolated inverter. Add it to your cart today!
