Surface-Mount Device (SMD) resistors in size 0402 are small, surface-mount components that combine precision and compactness, making it ideal for modern electronic applications. With dimensions of 0.04x0.02 inches i.e. 1.0 mm x 0.5 mm, they are ideal for high-density circuits where every square millimetre counts.
Metal film resistors are known for their stability, precision and low noise level, making them indispensable in applications requiring high reliability. these resistors are common in low-current circuits and are widely used in e.g. consumer electronics, medical technology and communication equipment.
Specifications:
- Power: 0.1 W (100 mW), adapted for low power loads.
- Size: Compact format of 1x0.5 mm, ideal for high density circuit boards.
- Material: Made of metal film deposited on an insulating substrate, providing high precision and stability.
- Tolerance: Typically ±1%, ensuring accurate resistance values.
- Noise performance: Metal film resistors have low self-noise levels, making them ideal for sensitive signal processing circuits.
Applications:
- Precision electronics: Used in measuring instruments and medical devices where precise resistance values are essential.
- Audio equipment: Ideal for amplifiers and other audio systems thanks to low noise levels.
- Industrial control systems: Stability and reliability make them suitable for long-term operation in industrial environments.
- Consumer electronics: Used in smartphones, computers and other compact electronics where space is limited.
Why choose SMD resistors in size 0402?
- Extremely compact design: Enables very high component density.
- Low parasitic capacitance and inductance: Advantageous in high frequency applications.
The small size makes these resistors optimal for ultra-compact electronic systems where every micrometre of PCB space is valuable and where low self-noise, parasitic capacitance and inductance are critical factors. 0402 are also compatible with automated assembly processes such as reflow soldering.
