KEMET’s product line includes surface-mount capacitors in aluminum, ceramic and tantalum and leaded capacitors in ceramic and tantalum.
Kemet Corporation – Capacitor Technologies
Broad selection of capacitor technologies in the industry across all dielectrics, along with an expanding range of electromechanical devices, electromagnetic compatibility solutions and super capacitors.
The name “KEMET” is a blend of the words “chemical” and “metallurgy.”
“…..Fortunately for KEMET, Bell Laboratories had also invented the solid tantalum capacitor, which complemented the use of low-voltage transistors (semi-conductors) in electrical circuits. Since Union Carbide had experience in the fields of high-temperature metals and alloys, the solid tantalum capacitor was chosen as KEMET’s “new product”.
High Voltage C0G FT-CAP
The HV C0G FT-CAP is ideal for a broad range of high voltage applications in which high volumetric efficiency and resistance to thermal and board stress are critical.
It offers low leakage current, exhibits low ESR at high frequencies and finds conventional use as snubbers or filters in applications such as switching power supplies and lighting ballasts. Their exceptional performance at high frequencies has made them a preferred choice of design engineers worldwide.

Riedon has been providing original equipment manufacturers with high-precision, wirewound resistors and committed customer service since 1960.
Wirewound, Thick & Thin Film, and also Foil resistive products used in industries such as Industrial Automation, Aerospace, Military and Instrumentation.
Riedon – High Precision Resistors
Custom RTD elements, Power resistors as heating elements. Compensation Resistors, Metal and Thick Film networks and arrays.
These Precision Shunt Resistors are designed for systems which have a fast changing electrical load. It has a Heatsink and is encapsulated in epoxy. The substrate is Alumina for Good Heat Transfer but with Electrical Insulation. It is a Resistor formed by a NiCr Foil. (Like Nichrome).
Precision Resistors – UNS 4-T220 – Riedon
- Resistance from 0.2 Ohm to 80 Ohms
- Power Rating to 15 Watts
- Resistance Tolerances to ±0.01%
- TCR to ±1ppm/K
- Load Stability to 0.01%
Resistors are probably the most common and well known of all electrical components. Applying a resistor to a circuit normally requires (1) calculating the nominal values needed in the circuit application (resistance, power rating, etc.) then (2) developing acceptable tolerances for the resistor that ensure it will function properly in all extremes of the application.
Read up the “Temperature dependence and TC” – The absolute ohmic value of a resistor is temperature-dependent. Also the “Definition of terms in the specifications of Resistors.”

SRT Resistor Technology and Passives
High Value Resistors in Thick film technology is a Specialization. Products include precision and power resistors, special Ceramic Chip Capacitors, Temperature Sensors and other High Grade Passive Electronic Components.
High Voltage in Small Size
In the expansion of the existing types of High Value and High Voltage resistor series, SRT is presenting at electronica 2006 under the designation HVR25 a leaded resistor, which has a working voltage of 15kV at a length of only 25mm.
By means of an optimized design for high working voltages, SRT has succeeded in realizing at this length and a width of 9 mm this improved version of High Voltage resistors. Compared with the type HVR30 with 30mm length, the working voltage could be increased by 5kV and the Voltage Coefficient (VCR) reduced by about 50%.
