Dear Valued Customer:
Voltronics has been offering high-performance, high Q, half-turn trimmer capacitors for over two
decades. The J-Series is a proven performer that delivers uncompromising stability for even the most
demanding applications, such as RFID, medical devices, cellular technologies, and much more.
In years prior, we offered the J-Series exclusively to the United States but through recent acquisition as
the manufacturer, we now supply the entire line worldwide.
As indicated in the pages of this brochure, we offer the series in a variety of packages and specifications.
Some additional information about the J-Series includes the following:
• We have sold tens of millions of J-Series components.
• They are the component of choice in thousands of designs worldwide.
• We offer direct-cross replacements for Sanshin part numbers.
• We offer engineering kits for all our J-Series components.
When your design demands indiscriminate performance, and when reliability becomes a high priority,
choose the very best, which is the Voltronics J-Series ceramic chip trimmer capacitors.
Sincere regards,
The Voltronics Team
World-Class Technology
Worldwide Availability
We now offer our JZ and JR series in a High-
Voltage package: the JZ_HV and JR_HV.
See pages 3 and 5 respectively for further
details and be sure to order your engineering
kits today!

Washing Instructions:
The J-Series trimmer capacitors can withstand cleaning cycles up to 10 PSI and have been used by customers for more than a
decade in many diverse environmental conditions. Without knowing your particular washing or cleaning environment, we
recommend these basic guidelines:
1) Water wash or isopropyl alcohol cleaning agents are acceptable providing that baths are clean and uncontaminated.
For maximum effectiveness, the cleaning process should occur immediately after soldering.
2) Either brush or spray methods are acceptable.
3) * Drying out components with forced hot air is highly recommended.
4) Also, we do recommend turning the tuning screw 3 or 4 complete revolutions prior to arriving at the final “set.”
* If a water wash process is used and water does get inside, we recommend that the parts be heated above 100C for a minimum of
