This is the example Product
Ferrite Beads
KEMET’s unique multilayer structure provides higher reliability and minimizes heat generation when filtering out high-frequency noise. Our ferrite beads are suitable for both signal and power lines and are commonly found in space-restricted applications such as wearables or PCs.
Film Capacitors
KEMET’s film capacitors have a low ESR that allows them to have a much higher ripple current rating without sacrificing their capacitance. Film’s high voltage rating makes them ideal for DC-Link and high-power applications. Their low ESR, efficient CV, and high voltage ratings make them very useful for energy storage, EMI filtering, and DC-Link applications.
Flex Suppressor®
These quick-and-easy-to-install ferrite sheets are designed for EMI noise mitigation and reducing de-sense caused by radiated emissions in RF circuits. Flex Suppressor® can be used to improve wireless power transfer and near-field communication circuits such as RFID. AEC-Q200-qualified products are also available.
Polymer Capacitors
KEMET is the market leader in polymer capacitor technology. Our organic capacitors are solid electrolytic devices with a conductive polymer cathode, capable of delivering optimized performance in a broad range of applications. Combining very low ESR and improved capacitance retention at high frequencies, with a broad dimensional offering, KEMET’s portfolio supports designers through innovation and technology.
Pulse Transformers
Pulse transformers are specially designed, common mode chokes that filter out any common mode EMI currents coming from the power line communication’s power transformer or the analog front-end of the modem. With support for up to 264 VAC and low insertion loss starting at 1 MHz, pulse transformers are an effective solution to pass EMI regulatory compliance, while allowing the desired signals to pass unaffected.
Supercapacitors
KEMET offers a large range of supercapacitors in surface-mount and radial construction with high-performance capabilities. Supercapacitors have characteristics that are common to both batteries and traditional capacitors. As a result, a supercapacitor can be used as a secondary battery when applied to a DC circuit. These devices are best suited for use in low voltage, DC hold-up applications such as embedded microprocessor systems with flash memory.
Tantalum Capacitors
KEMET’s broad MnO2 portfolio supports segment designers in telecommunications, industrial, automotive, military, and drilling applications where space limitations, voltage requirements, life performance, and maximum operational temperature requirements are a concern.
ADR Series
A new standard for DIN rail-mounting hydraulic-magnetic circuit breakers. The Heinemann ADR series is the evident choice for manufacturers willing to integrate their design with hydraulic-magnetic technology without additional redesign effort. In addition to all the advantages of hydraulic-magnetic circuit breakers such as precise, stable, and reliable protection against overload or short-circuits, ADR provides the same Fit and Form as standard MCB: a great advantage for simplifying refurbishment or technology upgrade.
Features
- Hydraulic-magnetic overcurrent and fast short-circuit protections
- Different tripping curves
- In-Rush capabilities (8x – 15x – 22xIn) in standard
- Changeover (SPDT) auxiliary contact (C-NO-NC) embedded on the same pole as the circuit breaker
- Different configurations and types of auxiliary contact connections
- Midtrip options: handle falls to horizontal position on electrical tripping
- Trip-free design: breaker cannot be defeated by holding the handle in the ON position
- Power to the circuit breakers can be fed from the line or load side
- Easy installation on DIN 35mm rail according to DIN 50022 (IEC/EN60715)
- Module width of only 17.5 mm (per pole)
- Captive screws cannot be lost
- Captive terminals
- Optional handle locking system for Logout/Tagout
C Series
The C Series is popular in outdoor locations, in either high-temperature or low-temperature environments where nuisance tripping might have been a problem in the past. The C Series is built for a wide range of applications and is one of the most versatile designs. From heating and air conditioning to modern railcars, the C Series breaker is built for the most demanding industrial applications.
Features
- Environmental, Vibration, and Shock Resistant: Mil-spec qualification for fungus resistance, humidity, salt spray resistance, and shock vibration resistance.
- Heat-Induced Nuisance Tripping Eliminated: The protector is designed to “hold in” at 100% continuous rated current, regardless of ambient temperatures from -40°C +85°C.
- Immediate Reset After Trip: The protector can be reset (closed) immediately after an overcurrent trip without a “cooling off” period.
- 1/2 Cycle High Inrush Tolerance – 8X (standard) and 25x: The protector is available with different levels of tolerance to 1/2 cycle current spikes. Standard tolerance is 8X the continuous current rating; in addition, 25X is also available.
- Overcurrent Curves, Long, Medium, or Short Delay: Time characteristic curves are available as Short, Medium, and Long Delay.
