Component Specifications

Definition
A passive electronic circuit component consisting of two or more resistors connected in series to divide an input voltage into a smaller, precise output voltage proportional to the input. In feedback applications, it monitors system voltage levels and provides scaled signals to control units for regulation and stability.
Working Principle
Operates on Ohm's Law and the voltage division principle where output voltage (Vout) = Vin × (R2/(R1+R2)). In feedback systems, it continuously samples circuit voltage, scales it to a measurable range, and feeds it back to comparators or microcontrollers to maintain desired voltage levels through corrective actions.
Materials
Resistors: Metal film (precision ±0.1-1%), thick film, or wirewound; Substrate: Ceramic (Al2O3) or fiberglass (FR4); Terminals: Tin-plated copper alloy; Encapsulation: Epoxy resin or silicone coating for protection.
Technical Parameters
  • Tolerance ±0.1% to ±5%
  • Power Rating 0.125W to 2W
  • Voltage Rating 50V to 500V
  • Resistance Range 10Ω to 10MΩ
  • Operating Temperature -55°C to +155°C
  • Temperature Coefficient ±25ppm/°C to ±100ppm/°C
Standards
IEC 60115, MIL-PRF-914, JIS C 5201

Frequently Asked Questions

What is the primary function of a feedback network voltage divider?

To accurately sense and scale voltage levels in a circuit, providing a proportional feedback signal to control systems for maintaining stable operation.

How do I select resistors for a voltage divider feedback network?

Choose based on required precision (tolerance), power handling, temperature stability, and resistance values that minimize loading effects while achieving desired voltage ratio.

Can voltage dividers be used in high-frequency applications?

Yes, but parasitic capacitance and inductance must be considered; use low-inductance resistors and proper layout to maintain accuracy at high frequencies.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
