Schaffner's new line of chokes come in a range of inductance values up to 90 mH and currents up to 5A. Vertical EV chokes have a narrow width, and the EH horizontal versions have a low profile. Designers can mount circuits densely due to low magnetic leakage flux. Unexpected resonance problems are prevented with a stable frequency response through broadband attenuation characteristics. They have a flammability rating of UL94-V0, and have operating and storage temperatures of -25C (-13F) to 100C (212F). They weigh 10-70g, and have a maximum operating voltage at 50 degrees of 250V. They also offer a power operating frequency at 50C (122F) of dc to 400 Hz, a maximum resistance tolerance at 25C (77F) of ± 15 percent, and an overcurrent of 1.5 x Inominal for 60 sec, once every hour.
Digital healthcare devices and wearable electronic products need to be thoroughly tested, lest they live short, ignominious lives, an expert will tell attendees at UBM’s upcoming Designers of Things conference in San Jose, Calif.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
