GEYER – Quartz Crystals and Oscillators without an Expiry Date

GEYER produces clock generators, manufactured according to the latest technical requirements:

  • Quartz crystals in tiny sizes, low frequencies and tight tolerances
  • Oscillators, including kHz frequency, in tiny sizes and low input currents

Quartz crystals and oscillators are mechanical resonators which can be stored for an unlimited time and used without temporal time limits. Prerequisite for optimal processing and the reflow soldering process is correct storage of the parts:

Storage conditions for crystals

RT -40°C to + 100°C, at MSL 1 = Relative Humidity (RH) up to 85%

Storage conditions for oscillators

RT -40°C to +125°C, at MSL 1 = Relative Humidity (RH) up to 85%

Correct storage is a coefficient for the function and durability of the component. Do you have demand for Crystal products in a defined specification or package? GEYER offers a wide range of Frequency Control products, including 5,000 specifications available from stock. GEYER can provide appropriate samples at short notice for your new designs.  Please let us know how we can help.

WIMA extends voltage ranges for MKS 2, MKS 4 and MKP 2

WIMA metallized film capacitors have been extended by several new voltage ranges e.g. 400 VDC for WIMA MKS 02, 800 VDC for WIMA MKP 2 or 850 VDC, 1600 VDC and 2000 VDC for WIMA MKP 4. In addition to that several new capacitance values have been introduced for WIMA MKS 4 and WIMA MKP 2.

With metallized capacitors, thin layers of aluminum are vacuum-deposited on the insulating film as conducting electrodes. In the case of a breakdown, the short circuit current causes the thin metal layer to evaporate around the point of failure and an insulating area is formed. The capacitor remains intact (self-healing).

Metallized WIMA capacitors are available with Polyester or Polypropylene dielectric in PCM 2.5 mm to 52.5 mm. Capacitance values range from 100 pF to 680 µF and rated voltages from 50 VDC to 2000 VDC.

GEYER has improved Aging on all small Crystal models

From now on, GEYER manufactures all small crystal models with a reduced aging of maximum ± 2 ppm (aging first year). 

With this step, they consider the risen requirements regarding tight tolerance and improved long-term stability for crystals, especially for wireless applications like WLAN, Bluetooth, RFID and ISM band radio.  The improved specifications are available for all SMD Crystals in case sizes from 1.6 x 1.2 mm to 8.0 x 4.5 mm, prepared for applications for extended temperature ranges like -40 to +85°C.  These crystals conform to RoHS standards and are specified for reflow soldering in accordance with J-Std-020.

LEDtronics Ballast-Ready/Dual Mode LED Tube Lights!

LEDtronics Ballast-Ready/Dual Mode LED Tube Lights Work with or without a Ballast

LEDtronics® announces their brand new DLC-Listed LED T8 Ballast-Ready/Dual Mode Tube Lights! These unique “Dual Mode” tubes work with or without a ballast!

LEDtronics always recommends doing a simple, one-time ballast bypass when first installing our LED lighting in order to gain the true energy and money savings obtained from our superior quality products.   However, they understand the need for Ballast-Ready products. LEDtronics is the true Solutions Provider of the LED industry, so they have the answer with their LED48T8BR series “Dual Mode” LED T8 Tube Lights. There’s no need for a ballast bypass when installing! All it takes is an easy direct retrofit into an existing 4-ft Fluorescent T8 fixture with an electronic ballast, and it’s ready to go!

Adding to that, when the ballasts do go out (which they will), you can bypass the ballasts. There’s no need to purchase new ballasts!
