Vishay aims to save space in automotive Class-D audio amplifiers with two independent inductors in the same package. Built into a 2525 case size (under 8 x 8 x 8mm), the AEC-Q200 qualified IHLD-2525GG-5A inductors are intended “to provide noise filtering in Class D amplifiers”, they “consists of two IHLP inductors with operating temperatures up to +155°C in one compact ...

Streamline Avionics (formerly Elpac Capacitors) has a series of general purpose metallised polyester film capacitors for filtering, coupling or bypassing in high or low impedance circuits within ac or dc applications. Called Z Series, they are available in three forms – axial oval wrap-and-fill, axial round wrap-and-fill and radial moulded box. They can be used in “applications that require long term stability ...

Vishay has created a series of high ripple current aluminium electrolytic capacitors for solar power converters. “Designed for solar applications, Solar 193 PUR-SI power capacitors offer rated voltage of 500V and useful life of 6,000 hours at a maximum operating temperature of 105°C,” according to New Yorker Electronics, which is stocking the parts. Rated ripple current is 2.52A at 450 ...

Smiths Interconnect has released a series of high frequency surface mount chip PCB line terminations. Called CTX SMT, and based on thin-film construction, the devices work across dc-67GHz and handle up to 1W of power. VSWR is typically 1.25:1, and 1.50:1 max in a 50Ω system, and 10x pulses can be handled (1µs at 1% duty cycle). Operation is up ...

Wurth added high saturation current versions to the ‘1206’ surface-mount shielded energy storage chokes in its WE-PD family  – see photo for general family appearance. Identified by ‘1260P’ (with the ‘P’ indicating a performance parts within the PD family) the parts use a different core material. The number indicated the part size – 12 x 12mm footprint 6mm tall. “Thanks ...

Panasonic is to add a smaller case size to ZS-Series of SMD conductive polymer hybrid electrolytic capacitors. Remaining 10mm in diameter, the new case is 12mm rather than 16mm tall. “The effect of the smaller size of ZS-series is to deliver higher performance while keeping the premium PCB real estate in check with a few millimeters leeway in height,” according ...

Knowles is saving space in power supply PCBs by offering edge-stacked ceramic capacitor assemblies. Intended for filtering in the input and output stages of switch-mode PSUs,  the parts are the ‘SV’ series. “The assemblies can be made with up to 10 chips of the same size with various lead configurations to safeguard against thermal and mechanical stresses,” according to product ...

Vishay is offering two options for high value of surface-mount capacitors with low equivalent series resistance. T55 series: 3.3μF to 1,000μF over 2.5V to 63V for power management, battery decoupling and energy storage TR3 series:  0.47μF to 1,000μF over 4V to 75V for decoupling, smoothing, bulk energy-storage and filtering “T55 series vPolyTan surface-mount polymer tantalum chip capacitors has recently been extended to include ...

Passive components from distributor, Anglia Components now includes multi-layer ceramic capacitors (MLCCs) and chip resistors from  Taiwanese manufacturer, Walsin. Capacitors, resistors, inductors, RF components and antennae will be included in the distribution agreement. In addition to expanding the passive components available, the signing also means there will be more choice if demand outstrips supply, for example with MLCCs. Walsin has ...

Panasonic has used conductive polymer technology to produce surface-mount aluminium electrolytic capacitors with 3mΩ max equivalent series resistance (ESR, 100kHz +20°C) in a 7.3 x 4.3 x 2.8mm package. The parts are intended as input or output capacitors on dc-dc converters. Maximum ripple current is 10.2A (100kHz +45°C – less at high temperature). Called the EEF-GY series, and under the company’s ...
