The advantages of PDC resistors are mainly reflected in the following six aspects, combined with their technological strength and market positioning, forming differentiated competitiveness:
1、 Vertical integration of materials and processes, strong quality controllability
Independent ceramic powder research and development: Control the entire process from raw material formulation to finished product manufacturing, ensuring the stability, voltage resistance, and consistency of resistors, and reducing external supply chain risks.
Special alloy materials: High purity, high thermal conductivity, and high temperature resistance materials such as manganese copper alloy and iron chromium aluminum alloy are used to enhance the reliability and environmental adaptability of resistors.
2、 High precision and low-temperature drift, excellent performance
High precision level: Supports precision levels such as ± 0.1%, ± 0.25%, ± 0.5% (based on JISC5202 standard), meeting the requirements of precision circuits.
Low temperature drift characteristics: The temperature coefficient (TCR) is as low as ± 15ppm/℃ (0 ℃ to+60 ℃), and the resistance change rate is ≤ ± 25ppm/℃ over a wide temperature range (-55 ℃ to+155 ℃), ensuring temperature stability.
Wide resistance range: covering 1 Ω to 10M Ω (E24/E96 series), supporting customized non-standard resistance values.
3、 High reliability design, adaptable to extreme environments
Rigorous testing verification:
Load life: Apply 1.5 times the rated power at+70 ℃ environment, and the resistance change after 1000 hours is ≤± (0.5%+0.05 Ω).
Welding heat resistance: Immerse the solder bath at 350 ℃± 10 ℃ for 5 seconds, Δ R ≤± 0.2%.
Pulse resistance: 10 times of 100 μ s pulse width, 2 times the rated voltage pulse impact, Δ R ≤± 0.1%.
Protective structure: The surface of the resistor adopts three layers of protection (glass glaze coating, epoxy resin encapsulation, vacuum coating) to enhance moisture resistance and corrosion resistance.
4、 Leading in high-frequency and miniaturization, in line with industry trends
Low inductance design: inductance value<1.0nH, reducing high-frequency signal loss.
Miniature packaging: Supports ultra small packaging such as 0201 and 0402, adapting to the space limitations of portable devices.
High frequency application support: optimized materials and structures, suitable for high-frequency scenarios such as 5G base stations and RF power amplifiers.
5、 Full scenario application coverage, strong customization capability

Industrial control: precision instruments, medical equipment, aerospace signal conditioning.
Consumer electronics: current detection and protection for smartphones and wearable devices.
Quick response to customized needs: providing personalized services such as non-standard resistance values, special packaging (such as 2225 large size), and high-temperature resistant materials.
6、 Environmental Compliance and Global Service Network
Environmental certification: Full range lead-free (RoHS/REACH compliant), halogen-free, helping customers gain market access through the European Union and North America.
First level agency system: Through partners such as Shenzhen Gujing Technology, we provide 24-hour global technical support, localized inventory management, and shorten delivery cycles to 3-5 days.
Quality assurance: Provide 36 months of free replacement service for non-human damage, and the technical support team provides circuit simulation models (in LTspice format).
