Wire Wound Chip power Inductors - PRODUCTS

The primary characteristics of Wire Wound Chip Power Inductors include high current-carrying capacity, low DC resistance (DCR), and a high Q factor. They also offer excellent thermal stability, high reliability, and effective electromagnetic interference (EMI) suppression. Furthermore, their wire-wound structure enables them to withstand mechanical shocks and pressure, making them well-suited for high-temperature and high-humidity environments.

Below is a detailed overview of the core characteristics of wire wound chip power inductors:
1. High Current-Carrying Capacity
The wire-wound configuration allows for higher current pass-through, making these inductors ideal for high-power applications. ZETEX’s ZWC, ZWP, and ZWS series products are specifically characterized by their high rated-current capabilities.

2. Low DC Resistance (DCR)
A low DCR minimizes power dissipation and maximizes energy efficiency. The wire-wound structure effectively lowers DCR, thereby enhancing overall power conversion efficiency.

3. High Q Factor
The Q factor (Quality Factor) represents the energy storage efficiency of an inductor. A high Q factor indicates lower energy loss and higher efficiency at specific frequencies. Wire-wound structures typically achieve a high Q factor, making them highly suitable for RF and filtering applications.

4. Excellent Thermal Stability
The core bodies of wire-wound inductors are constructed using alloy resistor materials that feature a low temperature coefficient of resistance (TCR). This minimizes variations in resistance across different temperatures, ensuring superior electrical stability. Select wire-wound inductors, such as those from Mayloon, comply with the SONY-SS00259 standard, further guaranteeing performance stability under fluctuating thermal conditions.

5. High Reliability
Molded Enclosure Design: Provides outstanding moisture-proof performance.
Laser Welding Technology: Ensures robust and highly reliable electrode connections.
Mechanical Resilience: Capable of enduring mechanical shocks and pressure, making them suitable for harsh environments with high temperature and humidity.

6. Application
Ideal for current-sensitive, voltage-divider, and electrical appliance power supply circuits.
Suited for high-power applications, including smartphones, GPS receivers, and RF modules.
Effectively suppresses electromagnetic interference (EMI) on the secondary signal side of electronic devices.
Bourns wire-wound chip inductors are particularly optimized for RF modules and EMI suppression.
