Passive Components
(Capacitors, Inductors, and Other Components)

To Customers Evaluating High Frequency and High Heat Resistant Capacitors and Inductors

The passive components used in 5th generation mobile communications systems (5G) require support for
high frequencies and high heat resistance.
For this reason, many evaluations are conducted on passive components, such as temperature characteristics evaluations,
insulation reliability evaluations, and joint reliability evaluations.
ESPEC provides products that can help reduce the work required for or help to automate these evaluations.

Test Systems

High Frequency Inductor/Capacitor
Temperature Characteristics Evaluation Test System

The inductors and capacitors used in 5G must support high frequencies. The performance of inductors and capacitors used in 5G also changes due to the ambient environment, so the characteristics of capacitors must be understood to assure the quality and performance of the product.
This test system enables automation of temperature step control and can automatically measure various characteristic evaluations with multiple channels.

  • High Frequency Inductor/Capacitor Temperature Characteristic Evaluation System
    • In the 1 to 100 MHz frequency range, this system can automatically evaluate measurements of electrostatic capacity (C), reactance (L), impedance (Z), and Q value.
    • Saves labor in tests by simultaneously measuring multiple channels.
    • Can conduct automatic measurements at preset conditions by working in conjunction with the temperature chamber.

Multi-Layered Chip Inductor Reliability Evaluation Test System

Multi-layer chip inductors are subject to damage due to disconnection caused by electric currents and heat generated over long-term use. This system can perform service life evaluations by supplying a constant current to the conductor coil at a high temperature.

  • Multi-Layered Chip Inductor Reliability Evaluation System
    • Evaluates service life by accelerating thermal strain inside the inductor with the application of a constant current under high temperature and measuring the change in resistance.
    • Applies current stress to specimens by working in conjunction with the temperature chamber and measures resistance.
    • Saves labor with a measurement jig that can be used to easily connect specimens.

Conductor Resistance Evaluation Test System

For passive components, conductor resistance evaluations that measure cracks in passive components and board connections that occur due to the thermal expansion and contraction of boards are becoming very important.
ESPEC systems can continuously measure the micro resistance values of conductor parts, such as solder joints and connector connections, in a temperature cycle environment that cycles between low and high temperatures.
These systems incorporate automatic measurements, data recording, and data processing by computer to efficiently perform more accurate connection reliability evaluations.
