TDK C1608X7R1H102K080AE 1000pF 50V X7R 10% Soft Termination 0603 Ceramic Capacitor 20 PCS

TDK C1608X7R1H102K080AE multilayer ceramic chip capacitor rated 1000 pF / 1 nF, 50 VDC, ±10% tolerance, with X7R dielectric in the 0603 / 1608 metric surface-mount package.

This part uses TDK’s soft-termination construction, designed to improve resistance to PCB flexing and help reduce the risk of ceramic cracking caused by mechanical board stress. That makes it especially useful in equipment exposed to vibration, assembly stress, thermal cycling, or repeated board flex.

TDK specifies an operating temperature range of -55°C to +125°C, maximum dissipation factor of 3%, and minimum insulation resistance of 10,000 megohms. The part is commercial grade rather than AEC-Q200 automotive grade. :chatgpt-content-reference{index="0"}

Original Mouser packaging identifies TDK C1608X7R1H102K080AE, 0603 size, 50 VDC, 1000 pF, X7R dielectric, soft termination, country of origin Japan, and date code 2139.

Lifecycle: ACTIVE.

HISTORICAL BACKGROUND: TDK was founded in Japan in 1935 as Tokyo Denki Kagaku Kogyo and became one of the world’s major manufacturers of magnetic materials, capacitors, inductors, sensors, ferrites, and other passive electronic components.

Multilayer ceramic capacitors became fundamental to compact electronic design because they provide useful capacitance in very small surface-mount packages. As PCB density increased, however, one weakness of conventional MLCC construction became more important: ceramic bodies can crack if the circuit board bends or flexes.

Soft-termination technology was developed to address that failure mode. TDK uses a more mechanically compliant termination structure between the ceramic body and the external electrode, helping absorb PCB strain before it reaches the brittle ceramic dielectric. This construction is particularly useful in boards subject to vibration, thermal expansion, connector insertion forces, depanelization stress, and mechanical flex.

The C1608 package corresponds to the widely used 0603 / 1608 metric size. This format offers a practical balance between compact dimensions, easy automated assembly, voltage capability, and serviceability.

X7R is a Class II ceramic dielectric designed for operation from approximately -55°C to +125°C with capacitance variation controlled within ±15% over its temperature range. The 1000 pF value is useful for filtering, signal conditioning, bypassing, noise suppression, coupling, and general electronic circuitry.

TDK currently lists the exact C1608X7R1H102K080AE as a production part, so it remains an active component rather than obsolete stock. :chatgpt-content-reference{index="1"}
