The XTL7030 Series features side-metal terminations for automated optical inspection (AOI) of the component during the solder reflow process. It offers inductance values from 10 to 47 µH. It also provides current handling (up to 5.3 A) and low AC + DC power losses. The XTL7030 inductors measure 7.1 mm square, with a maximum height of 3.2 mm. They are also qualified to AEC-Q200 Grade 1 standards (-40° to +125°C ambient), making them suitable for automotive and other harsh-environment applications. They measure 8.5 mm square, with terminals that elevate the inductor body 1.5 mm from the printed circuit board surface. The unique off-the-board construction allows standard power management IC packages (for example, QFN/VQFN) to be mounted beneath the inductor in a 3-D packaging arrangement. The XAR7030 is available with inductance values ranging from 0.16 to 10 µH. It also offers low DCR—as low as 1.26 mΩ. It features RoHS-compliant matte tin over nickel over phosphor bronze terminations and is also halogen free.

The 4-mm² reed relay, switching up to 1 A, 20 W, is the latest offering in the Series 120 relays from this vendor. The Series 120 is a range of single pole (1 Form A) reed relays that require a board area of only 4 mm x 4 mm, making it the highest packing density currently available, according to the vendor.

Two switch types are available: a general-purpose sputtered ruthenium switch rated for up to 20 W, 1 A, and a low-level sputtered ruthenium switch rated at 10 W, 0.5 A. The device has pins on a 2-mm square pitch. There are suitable connectors available from some manufacturers, both SMD and through-hole, which will allow these relays to be stacked in either a row or in a matrix on a 4-mm pitch.

The relays feature an internal mu-metal magnetic screen. Mu-metal has the advantage of a high permeability and low magnetic remanence and eliminates problems that would otherwise occur due to magnetic interaction. Relays of this small size without magnetic screening would be unsuitable for applications where dense packing is required, the company said. Pickering Electronics

The vendor of the SJ Series of thyristors (SCRs) calls them the first circuit-protection devices of their kind to offer a junction temperature of 150°C in compact surface-mount D-PAK (TO-252) packaging. These devices are also available in through-hole V-PAK (TO-251) packages. Standard SJ Series thyristors have a low gate current trigger level of 6 mA or 15 mA maximum at approximately 1.5 V. Sensitive models in the series feature a gate trigger current of less than 200 μA. These sensitive gate devices can be easily triggered by sense coils, proximity switches, and microprocessors. Compact D-PAK and V-PAK packages enable smaller board designs by making it possible to replace larger TO-220AB and TO-263 packages. Applications for SJ Series thyristors include capacitive discharge ignition (CDI) systems for motorcycle engines, portable generator engine ignition, strobe lights, and nailers as well as generic rectifiers, battery voltage regulators, converters, and inrush current-limiting circuits in AC/DC converters. They are also suitable for use in controls for power tools, home/brown goods (such as consumer electronics like televisions, radios, digital media players, and computers) and white goods/appliances.

The vendor considers the WE-DPC HV to be suitable for SEPIC, flyback, Cuk, zeta, and multi-output-buck converters application. It can be used as a power choke in series and parallel connection. WE-DPC HV offers functional isolation for 250-VRMS rated voltage. Würth Elektronik eiSos

Synchronous step-down silent switcher

The LT8650S, a dual 4-A, 42-V input synchronous step-down switching regulator, uses the vendor’s Silent Switcher 2 architecture—including four internal input capacitors as well as two internal BST and a single INTVcc capacitor—to minimize the area of the hot loops. Combined with well-controlled switching edges and an internal construction using copper pillars in lieu of bond wires and an integral ground plane, the LT8650S reduces EMI emissions. This improved EMI performance is not sensitive to PCB layout, simplifying design and reducing risk even when using 2-layer PC boards. The LT8650S can pass the automotive CISPR 25, Class 5 peak EMI limits with a 2-MHz switching frequency over its entire load range. Its synchronous rectification delivers efficiency as high as 94.6% with a switching frequency of 2 MHz. Its 3.0-V to 42-V input voltage range is suitable for automotive and industrial applications. The product’s burst mode operation ensures only 602 µA of quiescent current (for both channels), suited for applications such as automotive always-on systems, which require extended operating battery life. For the lowest noise operation, it can be programmed to run in forced continuous mode over the entire load range with spread spectrum frequency modulation. Its spreading frequency is programmable and synchronizable from 300 kHz to 3 MHz. Analog Devices Inc.
