Product Overview

The ZK series conductive polymer hybrid aluminum electrolytic capacitors are surface mount type capacitors designed for high-performance applications. They offer high capacitance and high ripple current compared to the ZC series, with excellent endurance of 4000 hours at 125. These capacitors feature low ESR and minimal dependency on frequency and low temperature, similar to polymer types. They are AEC-Q200 and RoHS compliant, making them suitable for demanding electronic equipment.

Safety and Legal Matters

Product specifications and applications are subject to change without notice. Always request and confirm the latest delivery specifications before purchase or use. This product is intended for general electronic equipment. Special applications requiring high quality and reliability, or those where failure could threaten human life, require prior agreement and specification documents. Ensure safety through protection circuits and redundant circuits in system design. Evaluate and confirm the state of parts after mounting in the actual operating environment. Compliance with RoHS Directive (2011/65/EU and (EU) 2015/863) is noted.

Matters to Be Observed When Using This Product

Avoid use in environments exceeding temperature limits, exposure to liquids, direct sunlight, corrosive gases, strong static electricity, or electromagnetic waves. Do not use in sealed structures by potting or molding. Ensure voltage is at or below rated voltage, especially under impact or pulse conditions. Improper use can lead to degradation, leakage, or destruction. Activated pressure relief valves emit high-temperature gas; keep face away. Avoid short circuits and conductive solutions. Product life is temperature-dependent; lower temperatures extend life. Ensure adequate space above pressure valves. Isolate capacitor case from cathode and circuit patterns. Do not reuse energized or dropped capacitors. Store within specified conditions (5C to 35C, 45% to 85% RH, blocked from direct sunlight) for no longer than the specified storage period (42 months for Hybrid series).

Circuit Design and Circuit Board Design

When connecting capacitors in parallel, avoid current imbalance. Do not place wiring patterns directly underneath surface-mounted capacitors on double-sided boards. For radial lead capacitors, ensure through-hole gaps match lead spacing to prevent stress. Provide adequate space above pressure valves for operation. Design circuits to prevent flammable gas from igniting. Be mindful of capacitor resonance. Isolate capacitor case from cathode terminal and circuit pattern. Laminate/outer sleeve is for information and not guaranteed insulation. Do not tilt, twist, or compress capacitors. Discharge capacitors through a resistor if necessary. Confirm ratings and polarity before mounting. For surface-mounted types, confirm terminal and land dimensions. For radial lead types, confirm terminal and hole intervals.

Mounting Conditions

Follow soldering conditions specified in the specification sheet. Surface-mounted types are for reflow soldering only. Radial lead types are not for reflow soldering. Avoid dipping the capacitor body in solder. Ensure other components do not contact the capacitor during soldering. Do not tilt or twist soldered capacitors. Using highly active halogenous solder flux may negatively impact performance and reliability.
