MLCC Replacement Solutions

KEMET KOCAP Tantalum Polymer Capacitors are ideal for board space savings, a piezo noise-free environment, high capacitance, long stable life performance, and/or lower profile requirements. Tantalum polymer capacitors are selected over other capacitor technologies when application voltages are less than 50V, capacitance needs are between 1µF to 1mF, and application frequencies are below 1MHz. Since replacing ceramic capacitors with tantalum polymer capacitors is not typically one-for-one, designers need to consider several design requirements as outlined in the schematic below.

Polymer Capacitors Cloud & AI Applications

KEMET Organic Capacitors (KO-CAP®) provide an ideal solution for applications requiring power-loss (hold up) protection or maximum power efficiency of a circuit with limited board space. Polymer technology offers high energy density and extended life capabilities, making it a key solution for designers working in cloud infrastructure applications like solid-state drives, 5G, and servers. In addition, with the AI computing edge trend pushing for high power, KEMET KO-CAPs are vital on 12V input and low voltage 1V CPU and I/O 3.3V and 5V power rails. These capacitors offer both long life and high ripple capability.

5G Cellular Products

KEMET Electronics 5G Cellular Products offer a variety of components for 5G applications and cellular networks. The product offering includes high-reliability components that can withstand high temperatures and harsh conditions found in 5G base stations. Capacitors and inductors are available in small case sizes and are ideal for smartphones and handheld 5G devices. Film technology components are designed for high-density 5G power supply requirements. KEMET 5G Cellular Products are suitable for both indoor and outdoor conditions.

Polymer Capacitors Industrial Segment

KEMET Organic Capacitors (KO-CAP®) offer higher voltages in smaller case sizes and are ideal for industrial applications. These capacitors deliver a solution for applications requiring power-loss protection or maximum power efficiency of a circuit when board space is limited. The polymer technology provides these capacitors with extended life capabilities in applications subject to extremely harsh environments. 

Group Switch Tank Converter Products

YAGEO Group (KEMET, YAGEO, Pulse) Switch Tank Converter (STC) Products are high-efficiency, high-density converters designed for non-isolated DC-DC applications. These devices operate by replacing the large magnetics typically used in converter designs with stacking voltages using switches and capacitors. The STC products are strategically placed between the input and DC-DC converter stages of the YAGEO group's Digital Architecture Passive Components. As a solution, these STC products take advantage of advanced semiconductor technology to support power supplies.

Polymer Capacitors Computer Segment

KEMET Organic Capacitors (KO-CAP®) are solid electrolytic capacitors with a conductive polymer cathode, capable of delivering optimized solutions for today and in the future. The KO-CAPs offer low ESR, improved capacitance retention at high frequencies, and a broad dimension offering, from large case sizes to sizes as small as 2012-10. This KEMET KO-CAP portfolio supports the designers in innovation and technology.

Group Input Stage Solutions

YAGEO Group (KEMET, YAGEO, Pulse) offers inductors, capacitors, and TVS diodes with a large variety of form factors and specifications. In a digital system, the input stage is the first step in ensuring data integrity, circuit efficiency, and safety protections. This is typically achieved with an inductor, capacitor, and a TVS diode for low-voltage systems.

T521 High Voltage Polymer Tantalum Capacitors

KEMET T521 KO-CAP® High Voltage Organic Polymer Tantalum Capacitors feature voltage ratings up to 75V and capacitance values up to 470µF, high ripple current capability, safe failure mode, and low ESR. These T521 capacitors are volumetrically efficient and have stable temperature characteristics. They are lead-free when ordered with 100% Sn termination finish, RoHS compliant, and halogen-free. These components are designed for DC-DC converters, power supply inputs, and higher application voltages such as 12V, 24V, 28V, and 48V input rails. The T521 KO-CAP Series features a Ta anode and Ta₂O₅ dielectric as well as a conductive organic polymer that replaces the traditionally used MnO₂ as the cathode plate of the capacitor. This results in very low ESR and improved capacitance retention at high frequency.

Group DC-DC Converters

YAGEO Group (YAGEO, KEMET, Pulse) strives to support 90% of all the passive technologies required in circuit designs. DC-DC converters saturate the electronics industry and are used to either step or step down the voltage and current requirements of the next stage in the circuit. In every variation of the DC-DC converter, current sense resistors, diodes, inductors, precision voltage resistors, and capacitors are used.

Tantalum Polymer Capacitors

KEMET Tantalum Polymer Capacitors are specially designed as a capacitance solution for applications seeking low ESR, high capacitance, long life, small case size, low profile, and high ripple handling. The use of a solid electrolytic capacitor in combination with a conductive polymer cathode yields the most energy-dense capacitance solution available in the world with the lowest possible ESR.
