We have wide range of Radial Aluminum Electrolytic Capacitor. jb’s JRG has the feature of Extremely Low impedance and High Long Life. Some of customer is using this series on UPS, power supply application. We can also customize the items for customers. The voltage can be produced up to 450V. As the same as the Load life, it is possible to customize it to 15000H.
If you need higher voltage, please send the email to us for more information. Please find the below is JRG feature.

* Load life of 10000 hours at 105°C
* High ripple current
* Miniature Series
* RoHS Directive Compliant

Keep growing and expanding the product line. Recently, there are two type of Polymer Aluminum Solid Electrolytic Capacitors that are launching. See below

PST-Low ESR Leadwire Polymer Aluminum Solid Electrolytic Capacitors
PSU - High Temperature Leadwire Polymer Aluminum Solid Electrolytic Capacitors

Both types are applicable to DC/DC converters and AC/DC converters, communication power supply, set-top boxes, router, TV, voltage regulator, mobile phone adapter (mobile phone charger), computer motherboard, graphics card, power supplies, CPU’s, Decoupling circuits and LCD Monitors.

The difference is the voltage range, PST has the voltage range of 2.5V ~25V.DC, on the other hand, PSU has the voltage range of 35V ~ 160V.DC. One series is low voltage bases, and the other one is high voltage. The operating temperature is -55°C~ +125°C.

Some customers of us require the Metallized polypropylene film capacitors with 4 pins, and we do offer it as JFQP series. Of course, with best price, short lead time and the most competitive price as usual. Jb is specialized in production of all kinds of capacitors, with 40 years production experience. If you are interested in it, please feel free to send us RFQs: info@jbcapacitors.com

One key factor that differentiates types of electronic components is they are passive or active.

Active electronic components are those that can control the flow of electricity. For examples: transistor, vacuum tubes, silicon-controlled rectifiers (SCRs).
Passive electronic components are those that don’t have the ability to control electric current by means of another electrical signal. For examples: capacitors, resistors, inductors, transformers, and some diodes.

JBR-3006 series through hole trimmer potentiometers, or "trimpots", intended for infrequent adjustment with features Panel Mount and Side Adjust
Please see JBR-3006 Series characteristics:

JBR-3296 preset or trimmer potentiometers are small “set-and-forget” type potentiometers that allow for very fine or occasional adjustments to be easily made to a circuit.
Rotary preset potentiometers are miniature versions of the standard variable resistor designed to be mounting directly on a printed circuit board and are adjusted by means of a small bladed screwdriver or similar plastic tool.
JBR-3296 series rotary potentiometer normally offers less than 300 degrees of angular movement from minimum to maximum resistance.

Trimming Potentiometers, do you need? It is an adjustable electrical component, they can be found in Precision equipment, like automobile switch, electric vehicle driver, radio control equipment, electric bicycle repair electronic scale.

Trimming Potentiometers are mounted directly on circuit boards, turned with a small screwdriver and rated for many fewer adjustments over their lifetime. It can adjust various problems of the circuit by itself. It has many shapes and can be applied to any device.

Anyway, please feel free to contact us if you need. Thank you
