Nothing is as small – Nothing responds as fast When an application requires thermistors with a rapid response time - the Semitec FT micro thin film SMD thermistor can be regarded as the golden standard. As one of the world’s thinnest temperature sensors, the Semitec FT outperforms similar products due to their miniature size, exceptionally fast response time and high heat resistance.
Miniaturisation One of their primary uses
is the thermal protection of IGBT and Sic MOSFET junction temperatures, especially when they are used in e-vehicle and other high-power applications. Their unique construction and miniature form (down to 0201) enables the FT to be placed closer to transistor junctions where it can quickly sense rapid changes in temperature, offering the user the best chance of sensing, controlling and smoothing temperature fluctuations. The overall benefit is that the IGBT’s output and lifetime can be maximised.

Medical profession under stress Even with the covid pandemic over, crises like declining revenues, rising expenditures and growing shortages of professional health care workers place greater pressures on medical equipment, which must connect to other systems and constantly exchange large volumes of data quickly, and in a secure, fail-safe and reliable manner. Devices for medical applications must be safe, error-free and quick to operate. ODU MEDI-SNAP plastic connectors provide high performance in the smallest possible installation space. They are touch-protected, fulfilling the requirements for 2 MOPP and 2 MOOP in accordance with IEC 60601-1. Available as push-pull or break-away, each connector can be mated to the correct socket, with individual
mechanical coding and with seven colour options for safe and intuitive operation. ODU MEDI-SNAP connectors are available in sizes 1, 2 and 3.5, with the largest version providing up to 41 signal contacts.

New Omron AC PCB Relay Delivers Its Highest Load Capacity
Omron Electronic Components Europe has extended its AC relay portfolio to provide its highest ever current and voltage capacity for AC PCB relays. The new G9KA-E operates with voltage capacity up to 1000VAC, and current up to 300A – one of the highest specifications in the current PCB relay market. Omron’s G9KA high-power relay series guarantees a mechanical lifetime of 100,000 operations. The ultra-low contact resistance of 0.2mOhm maximum minimises contact terminal heating allowing it to carry high current loads. The plunger-type relay structure provides high endurance and lower power consumption, whilst well-designed terminals
improve heat dissipation, further enhancing safety and longevity. Applications include grid-tie inverters and uninterruptible power supplies. The G9KA series can be applied to inverters for photovoltaic and energy storage systems. Specifically, the G9KA-E is suitable for use in 200-400kVA / 600-800VAC inverters. Omron’s G9KA-E AC PCB relay is also ideal for UPS input and output lines, providing disconnect from the grid and the load. A particular advantage here is G9KA-E’s suitability for power supplies that incorporate 100- 200kVA, 3-phase 400VAC input/output circuits.

Available through Powell Electronics are EESeal+ EMC filters from Quell offering improved attenuation and simple grounding Powell Electronics, the supplier of connectors and more for high-rel applications including defence, aerospace and industrial, is stocking Quell’s EESeal+ EMI filter inserts with improved attenuation and frequency mitigation. The inserts are easily and quickly inserted into standard connectors in seconds without the need for any special tooling or soldering, forming an effective EMI filter and maintaining the environmental seal. Customized samples are available at very short lead times. The products benefit from Quell’s patented EESeal+ technology which uses EMC filter components embedded into a silicone rubber insert that matches the size, shape and pin configuration of the connector to be filtered. Transient suppressors can also be included. Users can specify which filter elements are required for each pin, allowing for the creation of a completely custom filter insert with widely varying capacitor values, shorts and opens as desired. The EESeal+ technology benefits from lower contact resistance and lower inductance than standard EESeals due to the improved ground plane.
