It is a next generation replacement for the popular Allegro 312x and 314x lines of unipolar switches. The A1101 uses BiCMOS technology which consists of devices that feature fast power on time and low noise operation. Device programming is performed after packaging to ensure increased switchpoint accuracy by eliminating offsets that can be induced by package stress. Unique
The A1101EUA-T is a continuous time hall effect switch in 3 pin SIP package. It is a next generation replacement for the popular Allegro 312x and 314x lines of unipolar switches. The A1101 uses BiCMOS technology which consists of devices that feature fast power-on time and low noise operation. Device programming is performed after packaging to ensure increased switchpoint accuracy by eliminating offsets that can be induced by package stress. Unique hall element geometries and low offset amplifiers help to minimize noise and to reduce residual offset voltage which is normally caused by device overmoulding, temperature excursions and thermal stress. The device includes voltage regulator, hall voltage generator, small signal amplifier, schmitt trigger and NMOS output transistor.

Easy Install, Clear Wipe, So Far So Good
Size: H354 (14")
I put this on a 2016 Honda Pilot, and installation was quick and simple. It took me about a minute to remove the old blade and snap the new one into place. Your time may vary depending on how familiar you are with your rear wiper setup, but if you’ve swapped one before, this should be straightforward.
It’s only been on for a couple of weeks, but we’ve had a good mix of rain and car washes during that time, and it’s been wiping clean with no streaks. No squeaking, no smearing.
Shipping was on time, packaging was standard, and the price felt fair compared to other options I looked at. I know some Honda forums recommend just replacing the rubber inserts and sticking with OEM parts, but I didn’t know what brand was on the vehicle before. I ended up choosing Bosch mostly based on price and availability. For a rear wiper, it felt like a low-risk upgrade, and so far, I have no complaints.
The only thing I’d point out is that these blades come with a 30-day warranty, which doesn’t leave a lot of room to see how they hold up over time. That said, after the first couple of weeks, everything looks and performs just fine.

Fits my Honda Fit 2012 rear wiper
Size: H354 (14"), Size: H354 (14")
Easy to install and fits my Honda Fit 2012 rear wiper.
The wiper has a low profile but looks like a nice beefy wiper.
It wipes quite and smooth.

Fit passenger side on our 2023Subaru Outback.
Size: H410 (16")
Amazon said it did not fit our Subaru, but it is exactly what was needed for the passenger side. Easy to replace once you correctly determine which wiper arm your car has.

Fits great and no streaking.
Size: H281 (11")
I bought this for my 2015 jeep grand cherokee. Its easy to install, works great, no streaking, fits perfectly, and seems durable. I used rainx before and the rubber fell apart after 6 months. So I'm hoping this one lasts.
