In the wave of the Internet of Everything (IoE), IoT devices have spread to every corner of life. From smart homes to industrial production lines, from wearable devices to new energy systems, the millimeter-scale electronic components supporting this technological revolution are surface-mount device (SMD) resistors.
According to data from Zhongshang Industrial Research Institute, the number of global IoT device connections is expected to exceed 27 billion in 2025. Take smart homes as an example: each smart appliance is equipped with an average of over 200 SMD resistors, and the annual shipment of global smart appliances has exceeded 500 million units. The huge base of devices directly drives the continuous expansion of the SMD resistor market.
SMD resistors are widely used in circuits for automotive electronics, industrial control, new energy, home appliances, medical communications, consumer electronics, etc., thanks to their advantages of small size, light weight, high installation density, strong anti-vibration and anti-interference capabilities, and excellent high-frequency characteristics.
Application Cases:
In smart home systems, SMD resistors stabilize voltage for intelligent control modules.
In industrial IoT sensors, they ensure precise signal conversion under harsh environments.
With technological progress, IoT devices are developing towards "light, thin, short, and small", driving demands for SMD resistors to focus on:
Miniaturization and High Integration: Smaller packages (e.g., 01005) to meet ultra-compact circuit requirements.
High Precision and Reliability: Error control within 0.1% and low temperature coefficients for stable operation.
Green and Low Power Consumption: Lead-free materials and low-power designs for energy efficiency.
