MLCC alternative to film capacitors. These Monolithic Ceramic Chip Capacitors offer lower shock noise, less third armonic distortion, lower ERS, much higher dielectric breakdown voltage and lower capacitance drift.
In addition the MLCC series offer high resistance to higher soldering temperatures an issue, which is important for Pb free soldering process.

Murata Mfg Co. Ltd's SFSCE and SFSCD series of ceramic filters that feature a nominal center frequency of 10.7MHz to 22MHz and a bandwidth of 600kHz to 2MHz - twice the value of the company's previous products. Compactly finished in a low-profile design, the 4.5-by-3.8-by-1mm devices can withstand soldering temperatures up to 260°C.
The SFSCE10M7WF03-R0 features a nominal center frequency of 10.7MHz; bandwidth, ±500kHz and 2.2MHz; insertion loss, 6dB; ripple (within 3dB bandwidth), 2dB; spurious attenuation, 25dB and 30dB; and input and output impedance, 470 ohms.
The SFSCD20M0WF07-R0 has a nominal center frequency of 20MHz; bandwidth, ±630kHz and 3.2MHz; insertion loss, 6dB; ripple (within 3dB bandwidth), 2dB; spurious attenuation, 40dB; and input and output impedance, 330 ohms.

For high-reliability applications, Harwin has introduced the Datamate L-Tek and J-Tek SMT connectors, which offer an improved accuracy of co-planarity in situations requiring horizontal board mounting.


The Datamate L-Tek and J-Tek horizontal, surface-mount connectors use a new contact system that guarantees co-planarity of mould and contact. These male connectors come in a range of mounting options, with the ability to withstand very high bending and shear forces. They are available with latches, jackscrews or jackscrew board mounts and can be used reliably with pick-and-place equipment.

Conventionally, horizontal board-mount connectors employ a straight pin which is bent twice to produce a horizontal contact. This method can make it difficult to maintain the accuracy of co-planarity (the degree to which the component sits square on the board). If bent incorrectly, the connector will not sit on the board properly, creating handling problems with pick-and-place equipment. Datamate L-Tek and J-Tek connectors eliminate this hazard by using a contact system which is pre-stamped, avoiding the need for bending.

These connectors are suited to applications requiring high-reliability connectors in production volumes, such as high-end industrial equipment. They are available in RoHS-compliant and non-RoHS-compliant versions.

Harwin’s Datamate is a high-reliability connector system employing a four-finger beryllium-copper contact clip. It conforms with British Standard 9525-F0033 and can withstand high levels of shock and vibration in addition to a large number of mating cycles, all without loss of performance.

A 3-pin switch-mode LED driver IC with a regulated output current of 30mA was recently unveiled by Supertex Inc.
The new HV9923 can be operated from either a rectified universal AC line range of 85Vac to 264Vac or 20Vdc to 400Vdc.
According to the company, the pulse width modulated (PWM) peak current controller is ideal for driving multi-LED strings in off-line applications such as decorative lighting, architectural lighting, signage and incandescent replacements.

With an internal MOSFET (or Power Switch), the HV9923 reduces the external part count in LED designs to four components (excluding an EMI filter). The device is a fixed off-time PWM control IC that incorporates constant peak current feedback to maintain delivery of a 30mA current to the LED string.

August 2007, Portsmouth…Harwin the high performance interconnect maker, has announced that a comprehensive range of turret lugs - used in many applications to provide a strong, reliable wire to board connection – are detailed in its catalogue and website.


Turret s - also known as turret pins or terminals, are firmly attached to the PCB usually by riveting and soldering them through a hole in the PCB. The wire is then attached and soldered to the lug. This approach is often preferred for ease of assembly and because it provides a firm mechanical anchor for the wire against mechanical strain and vibration, as well as a secure electrical connection especially for larger diameter wires.

Turret lugs are used by many applications, including high quality valve amplifiers, transformers, and military projects, as well as the repair and maintenance sector.

The Airborn N-Series nanominiature connectors are designed for use in applications which require high reliability where extremely small size and weight are required.
The connectors, which meet or exceed requirement of DSCC 97031 and MIL-DTL-83513 for size, space, temperature and shock/ vibration performance, are ideal for a wide variety of military and commercial applications.
